This was the second switch in rtp_parse packet.
Normalizes time, if required, sets stream_index, etc.

some rtp servers assume client is dead if they don't hear from them.
.. so we send a Receiver Report to the provided ByteIO context (we don't have access to the rtcp handle from here)

open a new RTP parse context for stream 'st'.
'st' can be NULL for MPEG2TS streams to indicate that they should be demuxed inside the rtp demux (otherwise CODEC_ID_MPEG2TS packets are returned) TODO: change this to not take rtp_payload data, and use the new dynamic payload system.
